UPS delivers capacity-on-demand without increasing footprint

Fri, 09/13/2013 - 2:52pm


Emerson Network Power launched the Liebert APS uninterruptible power supply system (UPS) with FlexPower technology. The Liebert APS system supports power requirements of up to 20kVA/18kW. It eliminates the need to over provision, increasing operational efficiency and contributing to the UPS system’s low total cost of ownership (TCO). As a result, the system can achieve up to 92 percent efficiency in double-conversion mode, making it the highest efficiency UPS in its class. The Liebert APS UPS is available globally.

To enhance system availability, the Liebert APS UPS has a fully redundant design, allowing the critical load to run on conditioned power regardless of any single failure within the system. It has a wrap-around maintenance bypass, so the connected load can keep running while the system is being serviced. Its modular scalability allows Liebert APS system users to quickly add power capacity or back-up runtime to support changing rack equipment power requirements without powering down. The system is also available in transformer-based models that provide electrical isolation for even higher reliability. The Liebert APS UPS is enabled with Emerson’s LIFE remote diagnostic and real-time communication technology, which provides proactive maintenance, decreasing the average Mean Time to Repair (MTTR) and improving Mean Time Between Failures (MTBF).

The Liebert APS system is designed for small- to medium-sized sites that expect increasing power requirements as they upgrade to larger servers, add storage capacity and use more powerful processors to meet growing demand for resource-intensive applications. FlexPower modules allow power capacity to grow in 5kVA /4.5kW increments up to 15kVA/13.5kW or 20kVA/18kW. Battery modules may also be added as needed to increase backup time. FlexPower modules and battery modules are hot swappable, and can be added or replaced by the user.

The Liebert APS UPS can be installed in any data center or network environment – on raised or non-raised floors, or in standard rack enclosures. Three IntelliSlot ports allow multiple modes of communication and control. The UPS system has out-of-the-box compatibility with Emerson Network Power’s data center infrastructure management (DCIM) system, the Trellis platform, and is also compatible with the Liebert Nform and Liebert SiteScanmonitoring and reporting systems. The Liebert APS UPS includes Liebert MultiLink shutdown software for reliable and safe shutdown of protected applications.
